In classical social media RSs, the use of social information is relatively straightforward. For example, connections between users can be interpreted as a cue of similarity between their interests. For a CWB-RS, sharing content based on social connections may spread toxic content, however it can be useful if one of the connected users
has exemplary behavior. Moreover, social network structures affect not only information propagation but also decision and behavior [1]}. Thus in CWB-RS, some properties of the structure of the social connection graph of the internal community may be part of the objective. Still, the recommendation and creation of connections between diverse groups may sometimes lead to toxic behaviors, e.g. backfiring [2]}.
